The program uses the random number seed as the starting point to generate a number of random descriptions of fictional "demons": bizarre, supernatural creatures inhabiting some vague notion of "hells". The demons are unconnected with any specific religious tradition or work of fiction...though I suspect they might not be out of place in, say, Dante's Inferno. You can use these descriptions as starting points to create creatures for pencil-and-paper role-playing games (just as an example).
